And a big headline for these last weeks of summer. Lyme disease is on the move and the cdy now reports that ten times as many people are being infected as previously thought. What is going on? Abc's chief medical editor dr. Richard besser is here. What's behind these numbers? That's a huge increase? This is dramatic. The previous estimate was 30,000 cases per year. Now data, 300,000 cases of lyme disease every year, mainly in the northeast, increasing in the u.S. Mainly because of milder winters. Meaning the ticks last longer? They have a longer period in which they can bite. Let me ask you this because as you know I hate it when doctors say flu-like symptoms. Is there anything else that can alert you? The numbers are going up but the symptoms are the same. The key symptoms to watch for 80 percent of people are going to have a bull's eye rash and there is things like the flu, fatigue, chills, fever, headaches. Those are the typical findings. You said 80 percent who actually do get the rash don't necessarily get it right away? No. It can be a week or so. There are unusual symptoms you need to watch for, swelling of your knees, facial paralysis or weakness, severe headache, heart palpitations. If you have had a tick bite, you need to get it checked. Importantly, you have 48 hours from the time you are bit by the tick to get it off before disease is transmitted. Check into september and beyond. So important. Thank you dr. Richard besser.
